Witness Von Bellows told KPIX-TV that that the SUV was balanced such that an uneven distribution of weight could have slid the car further into the hole, which the Los Angeles Times reported was nine feet deep.

Ashok Narayanan, another passenger in the SUV, called the moment “terrifying.”

“We just felt that it might completely go down,” he told KGO-TV.

A rescue team eventually pulled the car out of the hole using a rope woven around nearby parking meters and connected to a tow truck, according to KPIX-TV. No one was injured, police said.

As for the cause of the sinkhole, San Francisco’s Public Utilities Commission pointed to a busted brick sewer main underneath the city’s street that dates back to 1875.

“Usually with sewers that old, age is likely the cause of the break,” spokesman Charles Sheehan told reporters, per the Times.
